She says the diet worked for her and her husband and she feels strong and healthy.

The keto diet has another big fan, influencer Amber Fillerup Clark. The Barefoot Blonde blogger recently shared her postpartum weight loss with a set of side-by-side photos on Instagram and credited the keto diet with her transformation.

One photo shows her at nine months pregnant and the other shows her six months postpartum. She's wearing the same strapless gray bikini in both images.

"I know it is so cliche to say but geez how crazy are our bodies?! Its amazing," she begins in the caption. "I wanted to post these progress pictures because where I saw the most changes was when I started doing keto with my hubby. He has done the keto diet on and off for 9ish years.. ever since I met him he has done it. He feels really good when he does it so he has just continued to do it."

Amber explains what her eating habits looked like while she was pregnant. "I am the type of person that if Im going to have a cookie Im gonna have a few and during my pregnancy I ate pretty much what I felt like while trying to make healthy choices.. but I have a maaaajor sweet tooth. I gained 50lb with each of my pregnancies."

Amber gave birth to her third child, Frankie, on February 18, and switched up her diet afterward. "So that has been the biggest change for me with keto is 1. Feeling so good being off carbs and sugar and 2. Seeing the most results to lose the baby weight I put on - just to feel strong and healthy," she writes. "I know its not for everyone but it works for us."

Amber responded to keto diet questions from followers and explained, "yes Im still nursing!" "She drinks only breast milk," she adds. Women are generally discouraged from being on any kind of diet while breastfeeding, but as long as you're getting enough calories (around 2,500 a day, according to the American College of Obstetricians and Gynecologists ) and nutrients, the keto diet shouldn't be an issue for your milk supply. "A mom on a keto diet would likely be able to keep her baby well nourished," Jennifer Wider, MD, a women's health expert previously told Women's Health .
